Modalert 200 may briefly alter parts of personality by increasing alertness, motivation, and attention, causing users to feel more confident, gregarious, or motivated. Some people report feeling more productive or emotionally muted, while others may feel irritable or anxious. These alterations are usually dose-dependent and temporary, fading off as the drug's effects wane. Long-term or frequent usage may cause dependency or subtle changes in mood and behaviour. However, it does not permanently alter essential personality characteristics. It is critical to monitor your mental state while taking Modalert and see a doctor if you observe any odd or persistent changes.
